BOTTLE-WASHING MACHINE. l

To all whom t may concern:

Be it known that I, JOSEPH W. DAwsoN, a

citizen of the United States of America. a V

ments, particularly adapted for use in bottle" washing machmes, one of the objects being to economize in the manufacture of machines of this kind. f

Prior to this invention very large bottle bottle'carriers including large heavy sprocket chains which travel through the-water in a bottle washing tank. Since the chains are subjected to the action of the water, it has been found necessary to make them of brass copper or other expensive material adaptey to withstand the action of the water. By arranging the sprocket chains in the manner hereinafter described, and by preventing the water from splashing onto the chains, the latter may be made of iron or other inexpensive material that is not adapted to withstand the action of the water. Since the chains are very long and quite heavy, the saving effected by the use of iron, instead of brass or copper, is a quite important item in the cost of the machine, and the comparatively inexpensive chains of my machine are as eiiicient and durable as the more expensive chains which are subjected to the action of the water. 1

vThe invention also includes other details of construction which will be hereinafter described. Y

Figure I is a side elevation of a bottle washing machine, embodying the features of my invention. Fig. II is a transversesection of the machine. Fig. III is a section taken approximately on the line III-*IIL f Fig. II. y

The machine I have shown toillustrate the preferred form of my invention, comprises a large tank having side walls 1 and 2, end walls 3 and 4, a bottom wall 5, and a partition wall 6 dividing the tank into compartments A and B.

Specification. of Letters Patent.

The bottle carrier comprises a pair of endless sprocket cha-ins 6, arranged at the eX- ter1or of the tank, and fitted to idle sprocket wheels 7 8 and 9 at the side walls of the.

A hood 14, arranged above the 'tank is pro-l vided with downturned fianges 15 having their lower margins arranged between the walls 13 of the chain guideways G, Fig. II. Angular brackets 16, secured to the hood 14, rest upon the wallsl12 of the guideways G so as to constitute supports for the hood.

H designates bottle holders extending A across the tankand secured to the sprocket chains 6 at the exterior of the tank. Each bottle holder comprises a series of bottle receiving pockets 17 secured to a channel bar 18, and angular arms 19 extending from the ends of the bar 18 and secured to the sprocket chains 6. 2O designates funnel shaped mem- Patented Feb. 8i, 1916.

bers (Fig. III) arranged immediately bey low the bottle receiving pockets 17 and 'adapted to receive thek long nozzles 21.

The bottles are introduced into the bottle holders at a point X, (left side of Fig. I) and discharged at the point X', at the right hand sidel of Fig. I. The bottle carrier is. moved step by step by means of mechanism which will be presently described` and when the `bottle carrier is4 at rest the 'nozzles 2l are inserted through funnel shaped members 20 and into the inverted bottles for the purpose of washing the inner faces of the bottles. AThereafter' the nozzles 21 are lwithdrawn from the bottlesto permit the bottle carrier to continue its intermittent movement. The inverted bottles are drained as they move toward the discharge point of the machine, and the water passing from the bottles flows into the compartments A and B.

The means for operating the bottle carrier comprises a power shaft 23, (Fig. I) a-pinion 24 secured to sai`d\power shaft, a gear the latter pinion 26 securedto gear wheel 25, a gear wheel 27 meshing with pinion 26, a shaft 28 secured to. gear wheel 27 and a crank arm 29 secured to said shaft 28. The crank arm 29 is shown in Figs. I and II. The mechanism just described is driven continuously to impart an intermittent movement to transmission devices'which move the bottle carrier step by step. These transmission devices include a wheel WV having a series of radial slots 30 adapted to ,receive the` crank pin 29 on the crank 29, and also having a series of arcuate faces 31 adapted to be engaged by the peripheral face of a disk 32 which is secured to the constantly rotating shaft 28. lVhen the mechanism occupies the position shown by dotted lines in Fig. I, the crank pin 29 is arranged in one of the radial slots 30, and a portion of the slotted wheel WV is located directly opposite arecess 33 in the disk-32. Then the crank pin 29 passes from engages one of the arcuate faces of the lwheel W, to ing. It will be noted that the wheel WV is v driven intermittently by thel constantly rotating crankarm 29, and that this intermittent movement is transmitted through a shaft 34 to a gear wheel 35 which meshes with a larger gear wheel 36, the latter being secured to the shaft 11 which constitutes the drive shaft for the bottle carrier. The sprocket. wheels 1() which drive the bottle carrier are secured to the shaft 11.

The long nozzles 21 are secured to water pipes 38 and 39 which form part of vertically movable carriages. The ends of the water pipes 39 are securedto cross heads v40,

are fixed to brackets 42 which are fastened to the side walls of the tank. The water vpipes 38 (Fig. III) are secured to cross --heads 43, slidably fitted to vertical guide rods 41, the latter being fixed to brackets 42. which are secured to the side walls of the tank. Flexible water supply tubes 45 lead from the water pipes 39 to afmanifold 46 secured to the tank wall 2. Thismanifold 46 is provided with three discharge ports to permit the discharge of water into the three 'flexible tubes 45, and it is provided with a single inlet port for the reception of a Water supply pipe 47. The water flowing from the Vsupply* pipe manifold 46, through the different flexible tubes 45, into the Water pipes 39, and is dise charged .through the nozzles 21 that are secured to the pipes 39. The water pipes 38, located in the compartment or reservoir VYA, Fig. III, are connected to-a manifold 4,6 by means of l flexibletubes 45. 50 designates a fresh waterI supply 'pipe secured to vthe manifold 46.

the radial slot in the wheel W, the peripheral face of the disk 32 prevent the latter -from turng being slidably fitted to verticalguide rods 41. The ends of these guide rods device.

47 passesinto the.

Thev fresh n water iowing from pipe 50 enters the manifold 46, flows through the flexible tubes 45', into the water pipes 38, and through the long nozzles 21 which communicate with said pipes 38.

There are three rows of nozzles 21 in the compartment or reservoir B and the bottles travel step by step, from one rowl of nozzles to another, so that each bottle is subjected to three washing operations in passf ing over the compartment B. After being Washed by the water flowing from the nozzles in ycompartment B, the bottles are thoroughly cleansed by the clean water flowing from the nozzles 21 in compartment A. The fresh water flowing from the supply pipe50 is zles in compartment A, so that the final Washing operationy is effected by the clean water obtaineddirectly from the main water supply pipe. The water discharged into the bottles at the upper end of compartment A, flows into said compartment and is afterward used for the primary washing operation whichv takes place at the upper end of compartment B. Each of these compartments is provided with an overflow opening 52 and a discharge pipe 53 leading from said opening. Water is drawn from the compartment A through a pipe 54 leadlng to a pump 55 which discharges the water into the pipe 47 'leading to the manifold 46.

conducted to the noz- The pump 55 may be constructed in any' suitable manner, and vit is preferably operated continuously to draw water from thc compartment A'and to force said water through pipe 47 and manifold 46 to the bottle washing device in compartment B.

As previously water tubes 39 in compartment B are secured to cross heads 40, the latter being slidably fitted to the guide rods 41. The pipes 39 and cross heads 40 constitute a vertically movable carriage, adapted to be raised to insert `nozzles 21 into the bottles, and adapted to be lowered to permit the bottle carrier to travel over the bottle washing The means for raising and lowering this carriage comprises a pair of arms 56 connected to the cross heads 40 by links 57. These arms 56 are rigidly secured to a rock shaft 58 which extends across the compartment B. The arms 56 are provided with extensions 59 adapted to v receive a counter-weight 60 which balances the weight of the bottle washing device in compart ment B. The bottle washing device in compartment A is raised and lowered through the medium of arms 56 secured to.l a rock shaft' 58', and provided with extensions 59 -which support a counter-weight 60. The

rock shafts 5'8 and 58 extendthrough a side wall of the tank, and they are operated through the medium of mechanism which is shownmost clearly in Fig. vThis mechapointed out, the horizontal I nism includes arms 61 fixed to the rock 61 and rock shafts 58 and 58, thereby raising and loweringthe bottle washing devices.

It is important to note that the sprocket chains 6, forming part of the bottle carrier, are located at the exterior of. the tank, while the bottle holders are arranged between the side walls of the tank. The flanges 15 depending from the hood 14 (Fig. II) and the side walls 13'of the chain guides G are arranged to form shields for preventing the water from splashing onto the sprocket chains 6. Each flange or shield 15 is located near and separated from a wall,.

or shield 13 to provide vpassageways for the angular end portions 19 of the bottle holder. By constructing and arranging the parts in this manner, the sprocket chains are protected from the water thrown by the bottle washing devices. The long heavy chains may, therefore, be made of cast iron or other inexpensive material, instead of brass, copper or other expensive material which has heretofore been used inthe manufacture of such chains.
